Motor pump assembly

Abstract

In a, in particular, portable motor pump assembly comprising an oil housing in which an electric motor and a pump and on which a manifold block as well as a cooling fan are mounted, the cooling fan is disposed between ends of the oil housing on an oil housing side wall. The oil housing is, except for at least one blow-out port, clad in an outer housing for guiding cooling air at least onto side walls of the oil housing, and the outer housing is fixed to the oil housing.

What is claimed is: 
     
         1 . A motor pump assembly comprising:
 an oil housing closed at both ends by closure lids;   at least one electric motor in the oil housing;   at least one pump in the oil housing;   a manifold block mounted on the oil housing and having valves; and   a cooling fan disposed between the ends of the oil housing on an oil housing side wall with a cooling air direction directed towards the side wall;   wherein the oil housing, except for at least one blow-out port, is clad in an outer housing configured to guide the cooling air at least over side walls of the oil housing, being fixed to the oil housing, and overlapping the side walls of the oil housing.   
     
     
         2 . The motor pump assembly according to  claim 1  wherein the cooling fan includes an electric drive motor and is mounted behind inlets of the outer housing to the side wall of the oil housing or to the outer housing. 
     
     
         3 . The motor pump assembly according to  claim 2  wherein the cooling fan comprises an outer casing, and the outer housing, as a border of the inlets, comprises an inner frame encompassing the outer casing. 
     
     
         4 . The motor pump assembly according to  claim 1  further comprising an additional cooling fan, wherein the cooling fans are arranged at two sides walls of the oil housing facing away from each other. 
     
     
         5 . The motor pump assembly according to  claim 1  wherein the oil housing has an approximately quadrangular outer contour and comprises cooling fins extending longitudinally on the outer counter along the side walls, and wherein the cooling fan has a supporting frame being C-shaped in cross-section and positioned at a distance from the cooling fins and fixed with hooks latched behind the cooling fins of two adjacent side walls. 
     
     
         6 . The motor pump assembly of  claim 5  wherein the supporting frame is adjustably fixed in the longitudinal direction of the oil housing. 
     
     
         7 . The motor pump assembly according to  claim 1  wherein the outer housing comprises two housing halves, each of which comprises housing walls overlapping three adjoining sidewalls and the ends of the oil housing. 
     
     
         8 . The motor pump assembly according to  claim 7  wherein each housing half is integrally formed. 
     
     
         9 . The motor pump assembly according to  claim 1  wherein the outer housing is attached to both ends of the oil housing. 
     
     
         10 . The motor pump assembly according to  claim 1  wherein the outer housing is attached to the oil housing with screw feet at a mounting side end and with attachment screws at the opposite end. 
     
     
         11 . The motor pump assembly according to  claim 1  further comprising a console attached to the outer housing with mounting screws fixing the outer housing at an upper end of the oil housing, the console comprising at least one suspension eye and/or a carrying handle. 
     
     
         12 . The motor pump assembly according to  claim 1  wherein external cable holders are provided on the outer housing for an electrical connecting cable and/or a control cable. 
     
     
         13 . The motor pump assembly according to  claim 1  wherein the outer housing is made of plastic and/or metal. 
     
     
         14 . The motor pump assembly according to  claim 1  further comprising a terminal box and an assembly control unit attached thereto, wherein the outer housing has a blow-out port that encompasses the manifold block and the terminal box, and wherein the blow-out port is configured to guide cooling air over the manifold block and the terminal box. 
     
     
         15 . The motor pump assembly according to  claim 1  wherein the outer housing comprises a slot-like blow-out port facing the side wall of the oil housing facing away from the manifold block and extending in a longitudinal direction of the oil housing. 
     
     
         16 . The motor pump assembly according to  claim 15  wherein the slot-like blow-out port extends approximately along an entire length of the oil housing. 
     
     
         17 . The motor pump assembly according to  claim 1  further comprising elastic pads provided between the outer housing and the oil housing.
